IMPROVEMENT IN WlNDOW-SASH Specification forming part of Letters PatentN0. 221,] 82, dated November 4 1879; application filed J due 17, 1879.

To all whom if-may concern:

Be it known that I, GEORGE H, PADGETT, of Edwards, in the county of St.Lawrence and State of New York, have invented a new and usefulImprovement in Windows, of which the following is a specification.

This invention relates to the manner of glazing or cementing the glassto the sash or frame.

Heretofore windows have been constructed by securing panes of glass to asash or frame having a simple rabbet to receive the same, first, bystrips of wood or metal; second, by the use of putty or cement upon theouter side of the window, the inner side of the glass bein g supportedby the shoulder of the rabbet. The glass is also commonly embedded inputty by first applying putty to the shoulder of the rabbet and pressingthe glass firmly into place, for the purpose of securing a perfectbearing for the glass and to render the connection of sash and glassmore nearly perfeet.

The first method is objectionable for the reason that it is expensive,and hence impracticable for the ordinary window. The second method isobjectionable because of the free access of moisture between the innerside of the glass and the shoulder of the rabbet, which the process ofembedding before described The pressing of the glass upon the bedding ofsoft putty squeezes it out irregularly, and leaves it to dry in a porousstate.

The condensation of the vapor in a heated room upon the surface of theglass by the colder air without produces a continuous state of moisture,more noticeable in cold weather, when water rapidly collects upon theglass and falls to the sash. This falling water re moves the paint fromthe sash at the base of the glass, gradually wears the wood away, and bythe force of gravitation permeates the imperfect bedding of putty, andis carried by capillary attraction to every part of the wood sash. Thiscondition of moisture loosens the putty upon the outside of the windowand causes it to cleave off.

The object of my invention is to construct windows so as to secure aperfect joining of sash and glass, also a smooth non -wearing body atthe base of the glass to resist the action of the falling water. p

i The invention consists in spreading putty smoothly upon the inner sideof the glass in a manner similar with the outer side, the putty thusappliedto form a part of and finish the design of the molded edge of thesash in its approach to the glass.

To accomplish this, first, I construct a sash after any of the approveddesigns, having the usual rabbet to receive the glass. I then make asecond rabbet, extending from the shoulder of the first rabbet towardthe inner side of the sash, of sufficient width for the purpose, and ofabout one-half the depth of the first rabbet. I then place the glass inits usual position, and fasten there with the zinc points commonly usedin glazing. I then proceed to apply the putty, first, for convenience,to the inner side in the second rabbet made for the purpose, and finishupon the outer side of the sash; or, second, a sash may have the singlerabbet only, and bevel the shoulder of the rabbet sufficiently toreceive the putty; or, third, the sash may have the single rabbet onlyand square shoulder, with the rabbet only of suffieient depth to sustainthe glass while glazing, and thus allow the putty to be spread upon thesash on the inner side Without giv ing the same an uncouth appearance.

I prefer the sash with the second rabbet to receive the putty.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is an elevation of a window-sash. Fig. 2is a cross-section of the same. Fig. 3 is aperspective of asash-railwith my improvement in construction.

A B represent the frame-work of the sash,

the manner of constructing which v iswell known to all mechanics inhouse-building, E being the inner molded edge of the sash, and

G the ordinary rabbet to receive the glass. At

D is shown the second rabbet, of sufficient in the usual manner at C andD, filling the rabbet at D, and completing the bevel or other design ofthe molded edge E, the putty at D forming a perfectjoining of sash'andglass, to the exclusion of all moisture and air, and forming a hardnon-wearing bod at the base of the glass.

I disclaim the ordinar process of embeddin gbefore described; also theordinary backputtying (by which the embedding is supplemented) on sashhaving a single rabbet with the shoulder a right angle, when only thespace formed by the irregular surface of the glass and shoulder of therabbet is filled with putty.

What I claim is- 1. A window-sash provided with a second rahbet, ordepression adjacent to the ordinary rabbet and inside the\vil'ldow-pane, and putty or the like applied therein, as and forthepurpose set forth.

2. The combination, with the sash having an additional rabbet ordepression inside the Window-pane, of putty applied therein inconforniity with the design of the molded edge.
